"I think you're bad for my mental health."
"I think you're just mean."
"Where do you get that idea?"
"You've been rude practically all morning!"
"..."
"On purpose."
"..."
"Don't have anything to say to that, do you?"
"Shut up."
"..."
"..."
"And now you're lapsing into sullen silence again!"
"If everything I say is going to be rude, I'm not saying anything at all."

This is, almost word for word, a real interaction between me and my brother this morning. At the end, he finally shut up and I spent almost half an hour focusing on my breathing.
HE DRIVES ME CRAZY!
He talks too much, he says things without thinking, and if he does think, then he's being deliberately hurtful! And he calls me a very uncaring person? He should look in a mirror!
He says I'm depressing to be around. That I'm have no imagination. He went and said that almost everyone in the house thinks I'm too sensitive!
I don't want anything to do with him. At all. But I can't make him leave me alone, we live in the same house...
I want to break something. I really do.
